Devices, systems, and methods for tissue specimen removal

摘要

A device facilitating removal of tissue includes a sheath and a deployable assembly deployable from the sheath. The deployable assembly includes a funnel, a proximal apex portion, a distal base portion, and a plurality of guards. Each guard defines a fixed end attached to a portion of an annular perimeter of the distal base portion of the funnel by a living hinge. In the deployed condition of the deployable assembly, the guards are disposed in a presented condition wherein the guards extend radially inwardly from the annular perimeter of the distal base portion of the funnel in overlapping relation relative to one another such that the guards extend across the distal base portion of the funnel to enclose an interior of the funnel. A containment bag for sealingly encapsulating the funnel therein is also provided as part of a system with the device. Methods of use are provided as well.
